Energy Transitions in the Atom
{"Image DocumentName": "Energy Transitions in the Atom", "Image ImageDescription": "If a collection of identical atoms are excited by a broad energy source (say an electric discharge) so that all of the excited states become populated, radiative de-excitation from the different states will produce an emission spectrum of emitted photons.  Different atoms will have different sets of possible emitted photon energies that are characteristic of that element. For example, when hydrogen is excited in this manner, the de-excitation transitions are shown in the diagram as an emission spectrum (called the Balmer Series \u2013 the only visible transitions) and the spectrum is viewed by using a spectrometer.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
